Previously only sernum_a was valid as both upper and lower parts of the serial number were being written to sernum_a. This left sernum_b as initialized.
This could break code as previously sernum_a contained sernum_b content
This pull request aims to align with expected intent of sernum_a and sernum_b.
Alternativley, changing line 166 to sernum_b would keep existing code functional.
Corrected serial number storage location.
